Beyerdynamic Pro 990 (250 Ohm)- Very detailed. Too much treble (And I like Treble!). Scooped out midrange really badly. It sounded like something was missing. Disappointed with it, but super comfortable.

Grado 60i W/ Senn Pads- Comfortable, but really ugly looking. Feels super cheap. For someone that only has only 70 bucks, it would be hard to top the sound quality. I feel like these are a great introduction to quality sound. Lack some bass.

HiFiMan HE-400- Nice sound, but electronic music sounds better on my Pro 900. Ortho drivers just do not do bass impact like dynamic drivers.

Ultrasone Hfi 780- Nice sound, but the Pro Line is much better. The Pro 900 kills it. If I couldn't afford it, this would be a nice alternative. The pleather pads heated up quickly, which was also annoying. The velour pads on the pros stay cool.

Ultrasone Pro 750 - I prefer the Pro 2500 to the 750.

Yamaha EPH-100 - My favorite IEM. Will have to purchase again when I have the chance!

ASG 2.5 IEM - Excellent sounding IEM, just couldn't get them to fit as comfortably as I'd liked.
